A small desktop model was released in February 2008 called the Virus TI Snow.
A revision of the TI series called TI2 came out in March 2009, featuring faster digital signal processing (DSP) controllers, additional polyphony, more effects in the effect section and a slightly changed design.
The Virus features a filter saturation stage as well as different types of digital and analog-style distortion.
The highly resonant twin multimode filter is also an important aspect of the Virus sound, the features of which have been extended in the Ti range to include grain table, comb and formant filter settings.
Both Virus filters can be connected in series, parallel or set to process two oscillators independently.
There were hardware alterations made to the TI such as the balanced inputs/outputs, 24 bit/96 kHz output and the new sequencer integrated interface.
It is much smaller, sporting a minimalist interface and utilizes a single DSP chip, giving it about half the polyphony and only four parts of multitimbral capability.
The Access Virus has been used extensively by trance and techno artists, including Headhunterz, Hardwell, Angerfist, Luca Anzilotti a.k.a.
John VIRGO Garrett III of Snap!, Paul Oakenfold, DJ Sammy and Sasha.
